Abstract
A composite closure for a container has a moulded plastics band (24) closed at one end by a plastics sure disc (72) which is held captive within a recess formed around the band interior. Also on the band interior is a screw thread (44) by which the closure may attached to a container neck (12). The disc is cut from flat plastics sheet and is initially plane. However, when the closure is fitted to the container a marginal edge region 78 surrounding the container neck is deformed downwardly to generally frustoconical form.
